Greetings All,
So I just bought a 2008 Dodge Ram Quadcab. Although the 20's with 33" street treads are nice looking and sporty......I would like something with a little more rubber and an aggressive tread pattern. Most of what I'm looking at either doesn't come in a 20" rim size and/or would be the wrong size tire.

My question is three fold. What is the minimum wheel size I can run? What is the stock back spacing on the 20" wheels? An if I switch rims what do I have to change on the Tire Monitoring System if I change rims, so that I don't have a light glaring at me?
Thanks,
Patrick

Im pretty sure you can switch to the ram 17s and clear your brakes.. I wouldn't run anything less than a 17. I also wouldnt run a rim with different offset that what the unit bearings are designed for ( So no rims with a shallow backspacing sticking way out)

And as for the tpms, you'll need to have a set of sensors installed in your new rims or the truck will not pick them up. and give you all kinds of warnings.
